' ITATION TILE AND PROCESS OF MAKING THE SAME.

eoaaaa.

To all whom it may concern:

Be it known that T, JOHANN ANTON LUTI a subject of the residing at Haarlem', Netherlands, have invented a new and useful Imitation Tile and Process of Making the Same; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to improvements in the manufacture of imitation tiles from cardboard for lining or decorating walls.

Various attempts have before been made.

to manufacture imitation tiles resembling faience tiles from cheap materlal, they have for example been made from sheet iron, but

- when this material is used, the color is apt to scale 0d and the iron becomes rusty. Sheets of cardboard have also been painted and subsequently cut into pieces of the size of :l tile. These tiles are not, however, satisfactory since they stick together during transport and also become detached from the wall when moisture gets into the joints.

The object of this invention is the manufacture of tiles from cardboard or paste board which shall be a good imitation of faience tiles by reason of there being a rounding or raising at the edges and also impermeable to moisture at their joints so that they do not become detached from the wall and which moreover have a glazed surface capable of withstanding spirits, turpentine, soap, acids, or the influence of the atmosphere or rain.

The figures of the drawing show, in crosssection, the blanks and tiles during the manufacture of the tile.

Figures 1 to 5 show steps during the manufacture of'paint-tiles and clouded tiles.

Fig. 1 is a section of the blank from which the tile is to be made; Fig. 2 shows the same with noisture resisting roughened backing applied; Fig. 3 shows a piece out from the blank the size of the tile; Fig. 4 show-s the disposition of the pieces for treating the edges; Fig. 5 shows a section of the tile during the last stages of the process and as completed; Fig. 6- is a section of a blank pressed in relief form for making relief form; Fig. 7 shows the same with filling in the depressions of the back face and an impervious roughened backing applied; and Fig. 8 shows a finished relief tile.

The tiles are manufactured as follows: Sheets 1 of thin card or paste board (Fig.1) are spread on each side 2, 3 with a'mixture of boiled and raw linseed oil in equal parts together with a drier. The back 3 is then spread with a layer 4 of the same mixture to which is added sharp sand and chalk.

(Fig. 2) to enable the cardboard to be pasted to the wall and capable of resisting moisture. The front 2 is now grounded with turpentine paint composed ofwhite lead and zinc-white in equal parts, and tur- 'pentine; After drying this operation is repeated and the front 2, is scoured with fine emery paper. The sheets of paste board are next cut into pieces 5 the size of a tile (Fig. 3); the pieces are placed one behind the other (Fig. 4;) and their edges 6 secured with emery paper and are coated with paint by a flexible roller 7 (Fig. 4), so as to reu der the joints impermeable to moisture. After this operation the pieces ofcardboard, hereinafter referred to as the tiles, are painted twice, and baked after each painting'in a mufile furnace at a temperature not exceeding 60 degrees centigrade.

By painting the tiles after they havebe en cut the color forms a small ridge 8 (Fig. 5) at the edges just 'as in real faience tile, so that when such tiles are pasted side by side to the wall the joints show the form of the joints of real tiling; whereas if the paste board had been painted first and then out into tiles only a colored card would have been obtained which would not be a good imitation of a tile.

The next operation is to glaze the tiles with a solution of acetone, aml-acetate, celluloid and nitrocellulose. This solution is very corrosive, for which reason the color must first be well baked in order to be able to withstand it. The glazed tiles are now dried in a mufi le furnace and the glazing will obtain a great brilliance, and Wlll also resist spirit-turpentine, soap, acids, and the influence of the atmosphere or rain, a result which cannot'be obtained by painting alone. By slightly varying the manufacture as described it is also possible to imitate glazed clouded English tiles. The material is as before cut into pieces of the size of a tile and the border rendered impermeable to moisture. ltnstead, however, of painting the tiles. After heating in a muflle furnace another layer of varnish is applied consisting -ff coating with varnish. After varnishing the of copal enamel (lacquer) only mixed with a little of the contrasting color, by which the gloss is obtained and the small white borders of the tile arefixed. It is essential in order to obtain this result that the card or paste board shouldbe cut into pieces before tiles are dried in a horizontal, position thencoated with the glazing composition previously referred to and again dried in a hot atmosphere. v

The process for making the relief tiles is as follows: Sheets of thin card or paste board 11 are first lief-form (Fig. 6 they are then spread on each side 12, 13 with a mixture of boiled and raw linseed'oil in equal parts together with a drier. After; drying, the depressions 13' on the back 13 are filled with white lead filling 13"; on the. thus prepared backside is spread the same linseed mixture as above, to which is added sharp sand and chalk 14 (Fig. 7). The front 12 is now grounded with white ground color; after drying, this operation is repeated. Thesheets. of paste board are next cut into pieces 15 of'the. desired size; their edges 16 are scoured with emery paper and coatedwith ressed in the desired reoil; after sometime the oil is dried by rubbing the edge with a cloth. After this operation the front side 12. of the tile and the edges are coated with stove enamel (lacquer) copal enamel (lacquer) in equal parts,

.mixed'with a light color.- Just as before,

a soft color'deposit is obtained'on the white ground color, having. a cloudy appearance;

further the rounded edges 18 (Fig. 8) and the small white borders 19 are also obtained, as above referred to. After heating in a muflle furnace, another layer of varnish is applied to the front and to the edges consisting of copal enamel (lacquer) only mixed with a color of another tint, to get a gloss. The tiles are now dried in a horizontal position, then coated with the glazing composition previously referred to and again'dried in a hot atmosphere.

I claim: 1. A process for the manufacture of quantities of imitation tiles of card-board or the like comprising the following stepsv executed in the order as named: cutting the sheets into pieces of suitable size for tiles; coating the narrow side-faces of said pieces with paint to protect them from moisture; coatmg thepieces with paint or enamel on the front. side, and ,drying themin a horizontal position, forming thereby a raised edge at the front side.

2. A tile consisting of a card-board blank having painted edge faces and a raised edge formed of coating material to its front face.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses. I
